我国制冷技术新突破！有望推动算力基础设施低碳运行

Core Insights - The research team from the Institute of Metal Research, Chinese Academy of Sciences, has discovered a new phenomenon called "dissolution pressure card effect," which could provide low-carbon and efficient cooling solutions for high-energy-consuming data centers [1][4] - The cooling systems in data centers account for nearly 40% of their total electricity consumption, and traditional compression refrigeration methods face efficiency bottlenecks when dealing with high power dissipation [1][4] Group 1: Discovery and Mechanism - The "dissolution pressure card effect" allows a solution of ammonium thiocyanate (NHSCN) to exhibit remarkable thermal effects under pressure changes, leading to a temperature drop of nearly 30°C within 20 seconds at room temperature [1][2] - This effect combines the refrigerant and heat transfer medium into one, utilizing the solution's flow to achieve efficient heat transfer while providing significant cooling through the dissolution and precipitation process [1][2] Group 2: Engineering Application - The research team has designed a four-step cycle system based on the "dissolution pressure card effect," achieving a theoretical efficiency of up to 77% and the ability to absorb 67 joules of heat per gram of solution in a single cycle [4] - This innovative method presents a potential breakthrough for next-generation cooling technologies in data centers, promoting low-carbon operations for computational infrastructure [4]
